Kanto Optical Corp. (関東光学株式会社, Kantō Kōgaku Kabushiki Kaisha) is a Japanese company that made the Amiflex 6×6 TLR in 1953–4.
"Kantō" loosely means East Japan, or the area of Tokyo as opposed to Kyoto and Osaka.
It is unknown if this company is related with the Ami 4.5×6 folder advertised during World War II.
